CHARLES @LEVEL ND. OHIO- BUFFER FOR CARS.

Application filed December 22, 1921. Serial No. 524,269.

.Cars, of which the following is a specifica- This invention relates tobuffers for cars, and has for its main object to provide a buffer whichis adapted to slide upon the rails of a track 1 01 reducing the jar inbringing .a car to a standstill.

Another object of the invention is :to proride a buflier .of simple andpractical .construction, which will support the rear wheels of a car forutilizing the weight to increase the braking power .of .;the buifer.

A furtherobject .of the invention is to provide a buffer of saidcharacter, which will be drawn back to its original position by the carwhen the car is moved away .after being brought to a standstill.

With the above .and other objects in view, as will be readilyunderstood, the invention will be hereinafter fully described asillustrated in the accompanying drawings, and the novel features{thereof will .be distinctly pointed out in the appended claims.

Similar characters of reference are used in the Several drawings todesignate corresponding parts.

Figure *1 is a side elevation of a track ,with a .car thereon, and abuffer constructed in accordance with any invention in position .uponsaid track for bringing the car to a standstill,

Fig. 2 is a .plan view .of the buffer upon the track as illustrated inFig. 1,

Fig. 3 is an end view of Fig. 2,

Fig. 1 is a side elevation of the buffer,

Fig. 5 is a similar view to Fig. 4, one side of the buffer beingeliminated, and the pull-bar engaging the axle of a car for drawing thebuffer back to its original position after the car has been brought to astandstill, and

Fig. 6 is a front view of Fig. 5.

Referring to the drawings, 1 represents rails fixed to cross ties 2, and3 a car carried by axles 1, which are supported by wheels 5 fortravelling upon said rails, all of ordinary construction. The buiferconsists of a pair of shoes 6 and 7, which are adapted to slidelongitudinally upon the rails of the track and support longitudinallyextending sidesS and9 connected by a transverse block 10. The shoes 6and 7 extend forwardly of the sides 8 and 9 for accomn'iodating thewheels 5 of the car 3, and said sides extend beyond face 11 of the block10 and their edges are curved inwardly at 12 to correspond with theperipheriesof said wheels. Depending flanges 13 and 14 at the outersides of the shoes 6 and 7 are adapted to engage the outer sides of therails of the track .to retain the buffer thereon. hen a car is :backedso that a pair of its wheels rest upon the forwardly extending portionsof the shoes 6 and 7 and said wheels engage the curved edges 12 of thesides 8 and 9, the buffer is forced or pushed along the rails .of thetrack and the weight of the car also tends to increase .the frictionbetween the shoes and the rails. thus bringing the ,car to a standstilland avoiding any sudden jarringof the car as is the case when striking afixed or stationary buffer.

In order to return the buffer to its original position when {the car isdrawn away after being brought to a standstill, a pull-bar 15 is pivotedat 16 between a pair of lugs 17 and 18 projecting from the face 11 ofthe transverse block 10, and its free end is provided with a suitablehook 19, which is adapted to engage the axle 4 of the car as the car isdrawn away. For disengaging the hook 19 of the pull-bar 15 from the axlel of the year when the buifer is again at its original position, a guidemember 20 is fixed to one of the cross ties -2 at such position asto beengaged by said pull-bar, and this muses the hook of the pull-bar to belifted clear .of the car axle, thus releasing the car and leaving thebuffer in its original position for the bringing of the next car to astandstill. The under edge of the pull-bar 15 is preferably swelled outat 21 to provide a cam for engaging the guide member 20. The buffer maybe set with the pull-bar 15 resting upon the guide member 20, or it maybe left at some other place along the track, in which case it isnecessary that the free or hook end of the pull bar should not be belowthe car axle. For holding the pull-bar so that its hook end will beabove the car axle, the pivoted end of the pull-bar is provided with adepending lip 22 for engaging the face 11 of the transversal block 10,and in order that the hook end of the pull-bar will slide over the caraxle, its lower edge is beveled at 23.

. position upon a track or used on different tracks for bringing a carto a standstill. It will be understood that slight changes in thedetails of construction maybe made within the scope of the claims.

Having fully described my invention, what I claim is: b

1. In a buffer, the combination of means adapted to slide upon a trackfor bringing a moving bodyto a standstill, a pull-bar, the pull-barhaving one end pivoted to said .means, and the other end of the pull-barbeing adapted to be engaged by the body when the body is moving in'onedirection to actuate said end of the pull-bar upwardly and to effectconnection with the body when the body moves in the other direction,substantially as described.

2. In a buffer, the combination with a car having an axle, of meansadapted to slide upon a track for bringing the car to a stand still, apull-bar, the pull-bar having its rear end pivoted to said means, a hookat the forward end of the pull-bar adapted to engage the car axle, thehook having a bevelled edge adapted to be-engaged by the car axle whenthe car moves rearwardly to cause the hook to pass over the car axle,

' and the hook being adapted to be connected with the car axle when thecar moves for wardly, substantially as described.

3. In a buffer, the combination of a block adapted to slide upon a trackfor bringing a car to a standstill, a pull-bar pivoted to the block, andthe pull-bar being provided with means for effecting a connection with acar when the car is withdrawn from the block, substantially asdescribed.

4. In a buffer, the combination of a block adapted to slide upon a trackfor bringing a car to a standstill, a pull-bar pivoted to the the car ismovedoff said shoes,

-means for effecting a connection with a car when the car is withdrawnfrom the block, and a guide member for causing the d1scon- ,necting ofthe pull-bar from the car as it moves, substantially as described.

. 6. In a buffer, the combination of a block adapted to slide upon atrack for bringing a car to a standstill, a pull-bar pivoted to theblock, the pull-bar having a hook at its free end for effecting aconnection with a car when the car is withdrawn from the block, and thepull-bar having means at its pivoted end for engaging said block to holdits free or hook end at a certain height, substantially as described.

7. In a buffer, the combination of shoes adapted to slide upon rails,sides supported by the shoes, a block connecting the sides, the shoesextending forwardly of said sides for accommodating the wheels of a car,the sides having curved edges forreceiving the Wheels of the car, andmeans for effecting the connection of the block to the car whensubstantially as described.

8. Ina bufi'er, the combination of shoes adapted to slide upon rails,sides supported by the shoes, a block connecting the sides, the shoesextending forwardly of said sides for accommodating the wheels of a car,the sides having curved edges for receiving the wheels of the car, apull-bar pivoted to said block, and the pull-bar having a hook at itsfree end for effecting a connection with the CHARLES HIERL.
